What are the advantages of ¼” cold rolled mild steel over stainless steel?
Cold rolled ¼” W44 steel is very uniform, long lasting and welder friendly. This is why it is recommended for outdoor water furnaces. In contrast, stainless steel is susceptible to stress corrosion cracking due to its high thermal expansion. Most stainless steel websites indicate that stainless steel is designed for cosmetic finish applications—automobile trim, architectural moldings, kitchen equipment, etc. Stainless steel units require oxygen to service i.e. repair welding. Mild steel is an ideal choice because of its higher strength, and lower susceptibly to cracking, leaks and broken seams due to the stresses and corrosive environment that outdoor wood furnace metals are exposed to while in use. There are several reasons why Portage & Main Outdoor Water Furnaces are made of 1/4″ W44 cold rolled mild steel—the best material for this application.
